This lens drive device is provided with: a first movable part; a second movable part; a first drive part; and a second drive part. The first drive part and the second drive part respectively have a first ultrasonic motor and a second ultrasonic motor. The first ultrasonic motor and the second ultrasonic motor are arranged on sides opposite to each other with respect an optical axis, and independently drive the first movable part and the second movable part in the optical axis direction.

A lens apparatus includes an operation member that is rotatable by a user operation, a zoom lens configured to perform zooming in accordance with a rotation of the operating member, and a detector configured to divide an entire zoom range from a wide-angle end to a telephoto end, and detect a zoom position of the zoom lens. A predetermined condition is satisfied.

A camera module includes first to third lens groups; a first mover configured to move the second lens group in the optical-axis direction; a second mover configured to move the third lens group in the optical-axis direction; a base accommodating the first mover and the second mover; a support ball disposed to be in rolling contact with the first mover, the second mover, and the base, the support ball supporting movement of the first mover and the second mover relative to the base; a driving magnet coupled to each of the first mover and the second mover; and a coil part coupled to the base, the coil part being disposed to face the driving magnet, and wherein an entirety of a surface of the driving magnet that faces the moving coil serves as a first pole.

An imaging apparatus to which an accessory apparatus is attachable includes a camera controller configured to communicate with the accessory apparatus. The camera controller receives first information on a data size receivable by the accessory apparatus, performs a setting for a data size to be transmitted to the accessory apparatus based on the first information, and communicate with the accessory apparatus based on the setting.

An optical apparatus capable of detecting an origin or the like even in a retracted state is provided. The optical apparatus includes a holding frame holding an optical system, an intermediate member, a driving unit moving the intermediate member in a direction along an optical axis of the optical system, a biasing member biasing the holding frame in a direction along the optical axis with respect to the intermediate member, and a detection unit detecting the intermediate member, and the optical apparatus also includes a first state in which a part of the holding frame is brought into contact with a part of the intermediate member according to a biasing force of the biasing member, and a second state in which the holding frame is separated from the intermediate member against the biasing force of the biasing member, in which the driving unit is able to move the intermediate member in a direction along the optical axis in either the first state or the second state, and the detection unit can detect the intermediate member at least in the second state.

An optical member driving mechanism is provided, including a first movable portion, a fixed portion, and a first driving assembly. The first movable portion is connected to an optical member. The first movable portion is movable relative to the fixed portion. The first driving assembly is configured to drive the first movable portion to move relative to the fixed portion.

Disclosed in an embodiment of the present invention is a camera actuator including a housing, a mover disposed in the housing and including an optical member, a tilting guide unit disposed between the housing and the mover, a driving unit which is disposed in the housing and drives the mover, and an elastic member disposed between the tilting guide unit and the housing, wherein the driving unit includes a first magnet disposed on a first side surface of the mover and a dummy member disposed on a second side surface of the mover facing the first side surface.

An embodiment of the present invention provides a camera actuator comprising: a housing; a first member combined with the housing; a mover including an optical member; a first magnetic body disposed in the first member; a second magnetic body disposed in the mover; and a tilting-guiding part for guiding titling of the mover, wherein the mover comprises a holder combined with the optical member and a second member combined with the holder, and the tilting-guiding part is closely adhered to the first member and the holder by repulsion between the first magnetic body and the second magnetic body.

An imaging apparatus and an imaging method that further facilitate recording of a video within an extraction range while moving the extraction range within an angle of view are provided. An imaging apparatus according to an aspect of the present invention includes an image sensor that captures a reference video which is a motion picture, a housing that accommodates the image sensor, a detection portion for detecting a motion of the housing, and a processor. The processor is configured to execute setting processing of setting an extraction range smaller than an angle of view within the angle of view in a case of capturing the reference video, extraction processing of extracting an extraction video within the extraction range from the reference video, movement processing of moving the extraction range within the angle of view over time in accordance with the motion detected by the detection portion, and recording processing of recording the extraction video during movement of the extraction range in the movement processing on a recording medium.

Disclosed are an image capturing system and method. In the image capturing system and method, a light path is changed by controlling a reflection angle of a mirror surface using a rotating mirror so that a single camera obtains consecutive images at various angles or at a wide photographing width.
